Can I fix my bricked LG G2?

I own a LG G2 D805 but I flashed a d802 rom for mistake and I got bootloop. I tried to flash stock d805 rom with LG Flash Tool 2014 but it failed...I tried to flash the d802 kdz and it worked (weird)..but when it boots, i get to the Android is upgrading, optimising 142 apps screen and it reboots after it finishes optimising, sometimes it reboots after I get to the home screen and when the device boots again it starts optimising the apps all over and then shows the set up screen for adding google account, wifi, etc. What should I do?
